IMPROVEMENT IN MACHINES FOR PERFORATING PAPER.

Specification forming part of Letters Patent No. 223,176, dated December30, 1879; application filed September 20, 1879.

To all whom it may concern:

Be it known that I, JAMES SEE, of Hamilton, Butler county, Ohio, haveinventcdcertain new and useful Improvements in Perforating-lllachines,of which the following is a specification.

This invention relates to machines for printers and Stationers use forforming rows of perforations in printed forms, 850., so that one part ofsuch forms may be easily separated from other parts.

The machine is operated by foot-treadle, and examples of the work it isintended to do may be found in sheets of postage-stain ps, incouponbonds, in coupon-tickets, stub-checks, Ste.

My invention consists of body-casting in T shaped form, containingguides for the crosshead, seats for table-brackets, and a seat for thedie of an arrangement of cored passages within the body-casting, incombination with litter-cups attached to the machine, so that thepunchings will all drain, into the littercups; of a table having doubleside ledges for squaring the sheets of paper 5 of an arrangement of acovered spring upon the base for retracting the treadle; of a yoke-barpassing through a mortise in the body-piece, and serving as a means ofuniting the cross-head rods to the treadle-rods of litter-cups fittedupon the yokebar in such a position that a depression of the bar isnecessary to unlock them so they may be removed; of a series of punchescombined with a clamp and a rigid truingsurface for bringing the punchesinto a straight line of a series of punches bedded in solder upon aflexible backing-strip, and of a punchclamp having a tongue to act as athrustingledge for the tops of the punches.

In the accompanying drawings, Figure 1 is a front elevation of mymachine 5 Fig. 2, a side elevation of the same; Fig. 3, a verticallongitudinal section of the body-casting Fig. 4, a plan of thebody-casting 5 Fig. 5, a vertical section of the upper parts of themachine; Fig. 6, a plan, enlarged, ofa section of punches; and Fig. 7,an elevation of one end of the die, stripper, and row of punches.

As shown in Fig. 1 the machine is formed with T-shaped body-piece Itbolted to a base, T. The side-extensions of the body-piece are boredvertically, and form the guides G for the crosshead rods F. Theeross'head A carries a series of punches, E, which effect theperforating by punching into a die fastened to the top of thebody-piece. The two cross-head rods F are connected at the bottom byayoke-bar, M, which passes through a mortise in the bodycasting. Rods Qconnect the yoke-bar M with the foot-treadle U, which is fulcrui'ned tothe base of the machine.

The die before referred to is fastened to the top of the body-piece, anda cored passage, 9, as shown in Figs. 3 and 4, in the body-piece causesall the punchings to fall through contracted openings into thelitter-cups L. These litter-cups are providedwith a pair of lugs,

which straddle the yokebar M. The littercups rise and fall with theyoke-bar, but are arranged so close to the projecting arms of thebody-piece that they can only be removed from the yoke-bar when theyoke-bar is in its extreme downward position.

As shown in Fig. 2, the treadle is fulcrumed to the base and impartsmotion to the cross head through the medium of the treadle-rods Q. Uponthe front of the base is bolted a cylinder, S, having a removable cover.Within this cylinder is a compression-sprin g, b, which is connected tothe treadle by means of a screwbolt, a. This spring tends to lift thetreadle into its normal position, and the nut upon the spring-boltserves to adjust the elasticity of the spring.

To the flat faces of the upper part of the body-piece H are bolted thetable-brackets I, which support the two tables J, whose top is levelwith the top of the die 0, as shown in Fig. 5. These tables have uponboth sides a raised ledge, V, set square with the row of punches, andthese ledges serve to guide the sheets of paper while being punched.

The upper part of Fig. 5 shows the crosshead, 850., in section. The rowof punches E is clamped between the inner true surface of the crossheadand the clamp O. A tongue,

2', upon the face of the clamp 0, serves to level the top of the punchesand to receive the thrust.

The punches E are attached to a light strip of metal, h, by being beddedin solder, and the strip is cut in sections, so that as much of the rowof punches as desired may be removed when stub-work is being done.

Fig. 6 shows a plan of a section of the punches greatly enlarged.

The inner face of the clamp U is beveled, so as to pinch the punches atthe bottom only of the clamping. This permits the punches to rock alittle, and thus accommodate themselves to the die and stripper.

The stripper K is attached rigidly to the die by screws and blocks ateach end, sufficient space being left between them to admit severalsheets of thick paper for perforating.

The punches slide through holes in the stripper, and are thus guided tothe die.

I claim as my invention 1. In a perforating-machine, the combination,with the cross head A, guide-rods F, and yoke-bar M, of the body-pieceR, having side arms, H H, and guides G at the extremities of the arms,substantially as set forth.

2. In a perforating-machine, the body-piece H, having the passage Grunder the die, combined with the litter-cups L, substantially as setforth.

.3. In a perforat-ing-machine, the combination, with the cross-head Aand guide-rods F,

of the yoke-barM and mortised body-piece R, substantially as set forth.

4. In aperforating-machine, the yoke-bar M, combined with thelitter-cups L, having straddle-lugs upon their bottoms for embracing theyoke-bar, substantially as set forth.

5. In a perforating-machine,- the combination, with the cross-head A andpunches E, of the loose clamp U, drawn to its work by bolts between itsupper edge and the upper end of the punches, substantially as set forth.

6. In a perfoiatingmachine, the combination, With the punches E, of thebacking-strip h, the punches being in solder upon the strip,substantially as specified.

7. In a perforating-machine, the combination, with the punches E andcross-head A, of the bolted clamp 0, having the thrust tongue 6,substantially as set forth.

8. In a perforating-machine, the combination, with the punches E andcross-head A, of the clamp O, holding the punches by its lower edgeonly, substantially as set forth.
